Description

Technical Field

[0001] This utility model relates to the field of glass polishing equipment, and in particular to a grinding disc base and glass polishing equipment for glass polishing. Background Technology

[0002] Existing glass polishing equipment includes a frame, a grinding disc base, a polishing disc, a lifting drive, a rotating drive, and a liquid supply structure. The frame has a grinding zone, and the various components of the grinding disc base are distributed in the lower part of the grinding zone. The polishing disc is located in the upper part of the grinding zone. The lifting drive and the rotating drive drive drive the polishing disc to move up and down and rotate, respectively, to grind the glass disc on the grinding disc base. The liquid supply structure is used to output polishing fluid to wet the workpiece on the workpiece fixture during operation. This type of glass polishing equipment has a low integration of the grinding disc base, resulting in a complex overall structure that is inconvenient for later maintenance. In addition, the dispersed arrangement of the various components of the grinding disc base increases the difficulty of adjustment and maintenance of the grinding disc base, and the processing cost is high. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing grinding disc bases, which have various components scattered on the frame of glass polishing equipment, resulting in a complex overall structure and inconvenience for later maintenance. This invention provides a grinding disc base for glass polishing equipment with high overall integration, which can be installed as a whole on the frame for use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The grinding disc base of a glass plate polishing equipment includes: an attachment part, at least one workpiece fixing structure, a vacuum negative pressure structure, and a first rotary drive mechanism. The attachment part is fixedly connected to the frame of the glass plate polishing equipment. The workpiece fixing structure is rotatably connected to the attachment part and includes a connecting platform, a shaft structure, a transmission mechanism, and at least one workpiece clamp. The shaft structure is suspended vertically at the lower part of the polishing area. The connecting platform is located at the upper end of the shaft structure, and the workpiece clamp is located on the upper surface of the connecting platform. The workpiece clamp is provided with an adsorption structure, and the connecting platform is provided with a first air passage communicating with the adsorption structure. The vacuum negative pressure structure includes a vacuum pumping device, which is connected to the first air passage. The first rotary drive mechanism is fixedly connected to the attachment part and drives the workpiece fixing structure to rotate through the transmission mechanism.

[0005] Compared with the prior art, the grinding disc base of the glass plate polishing equipment of this utility model adopts a modular design. The workpiece fixing structure can be set as an independent module, resulting in high overall integration. The grinding disc base is set onto the frame through the attachment part, which facilitates manufacturing, adjustment and maintenance, thereby reducing the setup and maintenance costs of the glass plate polishing equipment, simplifying its structure and saving space. The workpiece fixing structure and the first rotary drive mechanism are suspended vertically at the bottom of the polishing area, thus eliminating the need for excessive connection structures between them and the glass plate polishing equipment, reducing installation difficulty.

[0006] Furthermore, the transmission mechanism includes at least a first gear, which is disposed on the outside of the shaft structure; the first rotary drive mechanism includes a drive motor and a second gear, which meshes directly or indirectly with the first gear, and the drive motor is connected to the second gear in a transmission connection.

[0007] The above configuration allows for adjustment of the rotational speed of the workpiece fixing structure by controlling the gear ratio of the first gear and the second gear.

[0008] Furthermore, the workpiece fixing structure is provided in at least two, and the at least two workpiece fixing structures are spaced apart on the periphery of the first rotary drive mechanism. The first rotary drive mechanism synchronously drives the at least two workpiece fixing structures to rotate.

[0009] This invention can drive at least two workpiece fixing structures to work through a first rotary drive mechanism. The structure is simple and can effectively reduce equipment costs.

[0010] Furthermore, the workpiece fixing structure is provided in four parts, which are respectively arranged around the first rotary drive mechanism.

[0011] The above setup allows for the polishing of multiple glass sheets in a single operation, thereby improving the polishing efficiency of the glass sheet polishing equipment.

[0012] Furthermore, at least two workpiece fixtures are provided, and the at least two workpiece fixtures are spaced apart on the connecting platform.

[0013] By increasing the number of workpiece fixtures, multiple glass sheets can be polished in a single polishing operation.

[0014] Furthermore, the shaft structure is provided with a second air channel, the first air channel is connected to the adsorption structure and the second air channel, and the vacuum pumping device is connected to the second air channel.

[0015] The above setup allows the vacuum device to be connected to the shaft structure to control the adsorption function of the workpiece fixture on the control platform, reducing the difficulty of setting up the vacuum device and avoiding interference of the air duct with the rotation of the shaft structure.

[0016] Furthermore, it also includes a trough, which is set in the lower part of the polishing area of ​​the frame of the glass polishing equipment. The upper end of the shaft structure passes through the bottom surface of the trough, and a waterproof structure is provided between the trough and the shaft structure.

[0017] The tank serves as a protective sealing structure, effectively preventing water from entering the shaft structure and the first rotary drive mechanism. When the glass sheet is placed on the workpiece fixture, the vacuum negative pressure structure causes the glass sheet to adhere to the workpiece fixture. The first rotary drive mechanism drives the connecting table to rotate. After the glass is wetted by the polishing fluid, the polishing disc polishes the glass sheet. The tank collects the polishing fluid, preventing the polishing fluid and quartz sand from entering the shaft structure. When the polishing time is reached, the supply of polishing fluid is stopped, the first rotary drive mechanism stops working, and the vacuum negative pressure structure stops working, completing the polishing operation.

[0018] Furthermore, it also includes a liquid supply structure, which is used to output grinding fluid to wet the workpiece on the workpiece fixture during operation; the liquid supply structure is set independently relative to the workpiece fixing structure, and the water outlet of the liquid supply structure is located above the workpiece fixture; or, the liquid supply structure is set on the workpiece fixing structure, and the water outlet of the liquid supply structure is located around the workpiece fixture.

[0019] Another objective of this invention is to provide a glass polishing device using the aforementioned grinding disc base, comprising: a frame, a grinding disc base, a polishing disc, and a lifting drive device. The frame is provided with a polishing area; the grinding disc base is connected to the frame via an attachment and is disposed at the lower part of the polishing area; the polishing disc is disposed at the upper part of the polishing area; the lifting drive device is used to drive either the grinding disc base or the polishing disc to move closer to the other, so that the working part of the polishing disc abuts against the glass disc fixed on the grinding disc base.

[0020] Furthermore, it also includes a second rotary drive device, mounted on the frame, for driving the polishing disc to rotate in the opposite direction to the rotation direction of the shaft structure.

[0021] The second rotary drive device drives the polishing disc to rotate in the opposite direction to the rotation direction of the shaft structure, thereby increasing the polishing speed of the polishing disc. Attached Figure Description

[0027] The adsorption structure is a slot 10 that runs through and connects the upper and lower surfaces of the workpiece fixture 9.

[0028] The transmission mechanism includes at least a first gear 8, which is disposed on the outside of the shaft structure 6; the first rotary drive mechanism 11 includes a drive motor 12 and a second gear 13, which meshes directly or indirectly with the first gear 8, and the drive motor 12 is connected to the second gear 13 in a transmission connection.

[0029] The above configuration allows the rotational speed of the workpiece fixing structure 2 to be adjusted by controlling the gear ratio of the first gear 8 and the second gear 13.

[0030] The workpiece fixing structure 2 is provided in at least two, and the at least two workpiece fixing structures 2 are spaced apart on the periphery of the first rotary drive mechanism 11. The first rotary drive mechanism 11 synchronously drives the at least two workpiece fixing structures 2 to rotate.

[0031] This invention can drive at least two workpiece fixing structures 2 to work through a first rotary drive mechanism 11. The structure is simple and can effectively reduce equipment costs.

[0032] In this embodiment, there are four workpiece fixing structures 2, which are respectively arranged around the first rotary drive mechanism 11.

[0033] The above setup allows for the polishing of multiple glass sheets in a single operation, thereby improving the polishing efficiency of the glass sheet polishing equipment.

[0034] At least two workpiece clamps 9 are provided, and at least two workpiece clamps 9 are arranged at intervals on the connecting platform 3.

[0035] By increasing the number of workpiece fixtures 9, multiple glass sheets can be polished in a single polishing operation.

[0036] The shaft structure 6 is provided with a second air passage 7, the first air passage is connected to the adsorption structure and the second air passage 7, and the vacuum pumping device is connected to the second air passage 7.

[0037] The above configuration allows the vacuum device to be connected to the shaft structure 6 to control the adsorption function of the workpiece clamp 9 on the control connecting table 3, reducing the difficulty of setting up the vacuum device and avoiding interference of the air passage with the rotation of the shaft structure 6.

[0038] The connecting platform 3 includes an upper connecting part 4 and a lower connecting part 5. The upper connecting part 4 is disposed on the upper part of the lower connecting part 5. The workpiece clamp 9 is disposed on the upper surface of the upper connecting part 4. The upper connecting part 4 is provided with at least one first through hole (not shown in the figure) corresponding to the adsorption structure. The upper surface of the lower connecting part 5 is provided with a cavity 23 communicating with the first through hole at least corresponding to the position of the workpiece clamp 9. The first through hole and the cavity form the first air passage. The vacuum negative pressure structure is connected to the cavity 23 through the second air passage 7. The upper connecting part 4 and the cavity 23 are connected by a sealing connection (by sealing ring, etc.).

[0039] It also includes a trough 14, which is located in the lower part of the polishing area of ​​the frame of the glass polishing equipment.

[0041] The tank body 14 is provided with a liquid outlet 15 on the outside.

[0042] The bottom of the tank 14 is inclined to the side of the liquid outlet 15, so that the liquid flows in a directional manner toward the liquid outlet 15.

[0043] The tank 14 serves as a protective sealing structure, effectively preventing water from entering the shaft structure 6 and the first rotary drive mechanism 11. When the glass sheet is placed on the workpiece fixture 9, the vacuum negative pressure structure causes the glass sheet to adhere to the workpiece fixture 9. The first rotary drive mechanism 11 drives the connecting table 3 to rotate. After the glass is wetted by the polishing liquid, the polishing disc polishes the glass sheet. The tank 14 collects the polishing liquid, preventing the polishing liquid and quartz sand from entering the shaft structure 6. When the polishing time is reached, the supply of polishing liquid is stopped, the first rotary drive mechanism 11 stops working, and the vacuum negative pressure structure stops working, completing the polishing operation.

[0047] In one embodiment, the liquid supply pipe 26 and the second air passage 7 can be arranged inside the shaft structure 6 (two flow passages are provided in the accessory), thereby reducing the assembly difficulty of the parts and improving the production efficiency of the equipment.

[0048] The liquid supply device and the vacuum negative pressure structure are respectively connected to the liquid supply pipe 26 and the second air passage 7 through a rotary joint with a passage (or a structure or workpiece that can achieve the same technical effect). This allows the liquid outlet end of the liquid supply device and the air outlet end of the vacuum negative pressure structure to be fixed relative to the attachment part 21, while the liquid supply pipe 26 and the second air passage 7 can be rotated relative to the liquid supply device and the vacuum negative pressure structure, respectively.

[0051] Compared with the prior art, the grinding disc base 1 of the glass plate polishing equipment of this utility model adopts a modular design. The workpiece fixing structure 2 can be set as an independent module, with a high degree of overall integration. The grinding disc base 1 is set onto the frame through the attachment part 21, which facilitates production and manufacturing, and also facilitates adjustment and maintenance, thereby reducing the setup and maintenance costs of the glass plate polishing equipment, as well as simplifying the structure of the glass plate polishing equipment and saving space. The workpiece fixing structure 2 and the first rotary drive mechanism 11 are suspended vertically at the lower part of the polishing area, so that there is no need to use too many connection structures with the glass plate polishing equipment, reducing the installation difficulty.
